OGC:Drowning (5e Spell)

From D&D Wiki

You create an orb of water that engulfs a single creature within range.

The creature targeted must make a Strength saving throw. On a failure, the target takes 2d8 bludgeoning damage. If it is Medium or smaller, it is also grappled, with an escape DC equal to your spell save DC. Until this grapple ends, the target is restrained and unable to breathe unless it can breathe water or does not have to breathe, such as constructs and the undead.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 per spell slot level and you can affect Large or smaller creatures.
